Knee surgery: What supplements should I mention before knee or hip surgery?
Updated: Sep 20
Before undergoing knee or hip surgery , it's crucial to understand that prescription medications aren't the only factors that can influence the procedure and your recovery. Dietary supplements, vitamins, herbs, and other commonly used products can significantly impact the safety of the surgery.
Open and complete communication with your medical team, including your surgeon and anesthesiologist, is absolutely essential. Some supplements can increase the risk of bleeding during or after surgery, interfere with the effectiveness of anesthesia, or even negatively affect the wound healing process.

Why it's crucial to report your supplements before knee surgery or hip surgery
The importance of complete communication
Before any surgical procedure, such as knee or hip surgery , it is extremely important to inform your medical team about all the products you are taking. This includes not only prescription medications but also vitamins, dietary supplements, herbal remedies, and any other natural products. Complete and transparent communication is essential for your safety and the success of the surgery. You should always provide the medical team with a comprehensive list of all medications, vitamins, herbs, and dietary supplements you are taking, including dosages and frequency.
Risks associated with supplements
Many patients don't consider supplements to be 'medications' and therefore don't always mention them to their doctors. However, this omission can have significant consequences. The active ingredients in some supplements can increase the risk of bleeding during and after surgery, which could complicate the procedure and recovery. Furthermore, certain supplements can interfere with how your body reacts to anesthesia, affecting its effectiveness or causing unexpected side effects. Wound healing can also be compromised by some of these products, delaying your postoperative recovery.
Informing your surgeon and anesthesiologist about all the supplements you take is an essential safety measure. This information allows the medical team to anticipate potential interactions, adjust treatment plans, and minimize risks such as unexpected bleeding or problems with anesthesia, ensuring a safer surgical experience and a better recovery.
The challenge for the medical team
The widespread use of dietary supplements and herbal products presents a considerable challenge for healthcare professionals. Due to a lack of information or the belief that they are harmless, patients often fail to report them. This makes it difficult for the medical team to anticipate potential perioperative risks and drug interactions. Your body is a complex system, and the introduction of any substance, even a 'natural' one, can have effects that are not immediately obvious but are critical in the context of surgery. Therefore, providing a comprehensive list of everything you consume is one of the most important actions you can take to protect your health before knee or hip surgery .
Supplements that may increase bleeding risk during surgery
Identification of supplements with a risk of bleeding
Before undergoing knee or hip surgery , it's vital to know that certain supplements can affect your body's natural ability to clot blood. This interference can significantly increase the risk of excessive bleeding during and after the operation. Communication with your surgeon and anesthesiologist is essential to identify and manage these risks.
Some of the most common supplements that have been shown to have a potential anticoagulant effect or that may interact with medications that affect blood clotting include:
Glucosamine and Chondroitin: These supplements, often used for joint health, can interact with blood thinners such as warfarin, increasing the risk of bleeding problems.
Ginkgo Biloba: Known for its memory-enhancing properties, it can inhibit platelet aggregation, making it harder for clots to form.
Garlic (in high doses): Although beneficial for cardiovascular health, garlic in high concentrations can have anticoagulant effects.
Ginger (in high doses): Similar to garlic, ginger can influence blood clotting if consumed in significant amounts.
Fish oil (Omega-3): In high doses, omega-3 fatty acids can reduce the blood's ability to clot.
Vitamin E: High doses of vitamin E can have an anticoagulant effect.
St. John's wort: In addition to its interactions with many medications, it can also influence blood clotting.
Impact on surgery and recovery
The increased risk of bleeding due to these supplements can have several negative consequences during knee or hip surgery . Excessive bleeding can:
Require additional blood transfusions.
Prolonging the surgery time.
Increased risk of bruising and blood collections at the surgical site.
Delay wound healing.
Increase the risk of infections.
Extending hospital stay and overall recovery time.
For these reasons, it is crucial that your medical team is aware of all the supplements you take. They will be able to assess your individual risk and advise you on the need to temporarily discontinue certain supplements before surgery, as well as the appropriate time to resume them, always under professional supervision.
How certain supplements can affect anesthesia and wound healing
Interference with anesthesia
In addition to the risk of bleeding, it's crucial to understand that certain supplements can directly interfere with the anesthesia administered during your knee or hip surgery . This interference can manifest in various ways, affecting both the safety and effectiveness of the procedure. Some supplements can alter how your body metabolizes anesthetic medications, potentially leading to less effective anesthesia or, conversely, longer-lasting effects. This could prolong your recovery time in the recovery room or even cause respiratory or cardiovascular complications.
For example, some herbal products can have sedative or stimulant effects that interact with anesthetic agents, increasing the risk of over-sedation or, paradoxically, hindering the induction of anesthesia. Open communication with the surgeon and anesthesiologist is essential so they can adjust medication dosages or choose safe alternatives, thus ensuring your well-being throughout the surgical procedure.
Impact on wound healing
The wound healing process is complex and requires a series of coordinated physiological steps. Some supplements can negatively affect the body's natural ability to heal after knee or hip surgery . For example, certain products can influence the inflammatory response, which is an essential part of healing, but if excessive or insufficient, can compromise the integrity of the wound. Other supplements could affect collagen synthesis, a protein vital for the strength and elasticity of scar tissue, or even increase the risk of infection by altering immune function.
Poor wound healing can not only prolong your recovery but also increase the risk of complications such as wound dehiscence (opening of the sutures) or postoperative infections. Informing your medical team about all the supplements you take allows them to assess these risks and, if necessary, advise you on temporarily discontinuing certain products to optimize your healing process.
Certain supplements can alter the body's response to anesthesia, prolonging recovery or causing unexpected effects. They can also compromise wound healing by affecting inflammation or collagen production. Informing the medical team is vital to prevent complications and ensure optimal recovery.
General recommendations for supplement management before surgery
The importance of a complete and honest list
Before undergoing knee or hip surgery , one of the most important steps you can take for your safety is to prepare a comprehensive list of all the supplements you take. This includes vitamins, minerals, herbal products, natural remedies, and any other dietary supplements, no matter how harmless they may seem. It is crucial that this list be given to your medical team, including the surgeon and anesthesiologist, well in advance of your scheduled surgery date. Do not underestimate the impact that even a seemingly benign supplement can have on your body's delicate balance during a surgical procedure.
The information should be as detailed as possible, covering:
The exact name of each supplement.
The dose you take (for example, milligrams or units).
The frequency with which you consume it (daily, weekly, etc.).
The reason why he takes it, if known.
How long have you been taking each supplement regularly?
This thorough communication allows the medical team to assess potential interactions with the medications that will be used during surgery, as well as risks specific to your individual case, and to make informed decisions about your surgical and anesthetic plan. Your honesty and thoroughness in this step are essential to preventing unexpected complications.
When and how to stop taking supplements
It is vital to remember that you should not discontinue any supplement on your own without first consulting your doctor. The decision to stop using a supplement, and the appropriate time to do so, should always be based on personalized medical advice. Some supplements may need to be discontinued several days or even weeks before surgery to allow their effects to completely disappear from the body and minimize risks. This is especially true for those that affect blood clotting, blood pressure, or that may interact negatively with anesthesia.
Your doctor will provide you with clear, personalized instructions on which supplements to stop taking and when, as well as when it would be safe to resume them after your surgery. It is crucial to follow these instructions precisely to avoid complications that could jeopardize your health or delay your recovery. If you have any questions or remember to take any additional supplements, it is always best to ask your healthcare team. Transparency and adherence to medical guidelines are key to a safe surgical experience and a successful recovery from your knee or hip surgery .
Specific supplements to discuss with your doctor before knee surgery or hip surgery
While the general recommendation is to disclose information about all supplements, some, due to their properties and common use, deserve special mention and detailed discussion with your surgeon and anesthesiologist before any knee or hip surgery . Proactive communication is key to preventing complications and ensuring a safe procedure.
Glucosamine and Chondroitin: A special case
Glucosamine and chondroitin are widely used supplements for people seeking relief from joint pain and improved cartilage health. However, their popularity does not exempt them from potential interactions. It is crucial to know that these supplements can interact with blood-thinning medications, such as warfarin. This interaction can increase the risk of bleeding during and after surgery, which is a significant concern. Therefore, if you are taking glucosamine or chondroitin, it is imperative that you inform your medical team so they can assess the risk and advise you on the need to temporarily discontinue them before the procedure.
Other herbal and dietary supplements for care
Beyond glucosamine and chondroitin, a wide range of herbal and dietary supplements can present perioperative risks. As mentioned, products such as ginkgo biloba, garlic (in high doses), ginger (in high doses), fish oil (omega-3), and vitamin E can influence blood clotting. Others, such as St. John's wort, are known for their multiple drug interactions, which could affect anesthesia or postoperative medications. The widespread use of these products presents a challenge for clinicians due to the potential risks and drug interactions that can arise.
Open communication with your medical team is essential. They need to know about every supplement you take to anticipate any potential problems, whether it's an increased risk of bleeding, interference with anesthesia, or a negative impact on wound healing. Don't assume a supplement is harmless just because it's "natural" or available over the counter. Your health and safety are the priority.
Before knee or hip surgery, it's vital to discuss supplements like glucosamine and chondroitin with your doctor due to their potential interaction with blood thinners. Similarly, other herbal and dietary products can affect blood clotting, anesthesia, or wound healing. Complete transparency with your medical team is essential for a safe surgery.
In short, preparing for knee or hip surgery goes beyond following standard pre-operative instructions. It is essential that you, as the patient, take an active role in your safety by informing your medical team about all supplements, vitamins, and herbs you use. This transparency is crucial to preventing risks such as excessive bleeding, interactions with anesthesia, or problems with wound healing.
Open and honest communication with your surgeon and anesthesiologist will allow the surgical plan to be tailored to your individual needs, minimizing complications and optimizing your recovery. Remember that no supplement is completely harmless in the context of surgery, and your medical team is the only one qualified to assess its impact.
